Odyssey Stratus or Parasound Halo A23?

this is not your avr-4800 have you even seen the 2000ivr let alone heard it?

I apologize. I'm sure the 2000 is a distinct improvement. But I don't think it has the overwhelming power to easily drive those speakers without any strain at all. For example, the Denon can't drop below a speaker load of 4 ohms and would prefer 8 ohms. The automatic cutoff would kick in. The B&K's can drive below 1 ohm that's high current capability. I use it to drive 4 pairs of speakers simultaneously stacked to the ceiling -4 tweeters and 8 -6 inch midrange woofers on each side- a wall of sound. The impedance to the amplifier is below 1 ohm and would short most amps.

sstark, I'm the original owner of a pair of M-200 monos since 92, they're in mint cond. I outfitted them with two pairs of cardas output posts on each amp and two Shunyata Mojave P/C's, they sound fantastic,..... even if I get new amps, I'm keep'n the B&K's, they're that good.

I agree with you. I have 2 sets of M200's and a 202plus and my son just bought a used M200. Their sound for the bargain price is unmatched. Pairing them with a tubed preamp AI and they really sing. Sadly, I just checked and saw none for sale on Audiogon or Ebay.

Stratos...much nicer amp in my opinion. I have Paradigms and the Stratos took my experience to a whole new level of detail.
